Having textured implants in few days, is textured implants more likely to trigger immune response than smooth?

It sounds like you have answered your own question. Capsules will form with most foreign objects placed inside the body. I prefer the smooth round implants for a softer feel and fewer long term risks.

Dear amylouise23,
there have been numerous studies on the safety and efficacy of silicone breast implants. The FDA has approved them to be safe and breast augmentation is the most common cosmetic surgical procedure performed in the United States every year. Implants are much different than they used to be with rigorous testing and cohesive gel. I can't tell you how happy my breast augmentation patients have been with their implants.
I would recommend a consult with a plastic surgeon to go over all of your concerns. Saline implants are also a perfectly good option if you are still concerned and are less expensive.
